Customizing the Data Protector Environment

Using Omnirc Options

•OB2VXDIRECT: Enables direct (without cache) reading for Advanced VxFS filesystems, as well as improving performance.

•OB2PORTRANGE: This option limits the range of port numbers that Data Protector uses when allocating listen ports dynamically. This option is typically set to enable the administration of a cell through a firewall. Note that the firewall needs to be configured separately and that the specified range does not affect the Inet listen port.

ExampleOB2PORTRANGE=40000-40199

This sets the port range to ports from 40000 to 40199.

•OB2PORTRANGESPEC: This option allows you to specify a range of port numbers for every binary. This mechanism gives you more control over the ranges and helps to keep their sizes smaller. Note that the firewall needs to be configured separately and that the specified range does not affect the Inet listen port.

For configuration examples, refer to “Firewall Support” on page 528.
